Minolta SR-mount
The Minolta SR-mount was the bayonet mounting system used in all 35 mm SLR cameras made by Minolta with interchangeable manual focusing lenses. Several iterations of the mounting were produced over the decades, and as a result, the mount itself was sometimes referred to by the name of the corresponding lens generation (f.e. "MC", "MD" or "X-600") instead. All lenses for these mounts are interchangeable between older and newer Minolta manual focus 35 mm film SLR bodies. There are exceptions, such as, the lenses before 1961 feature a slightly different aperture leverage, and thus the automatic diaphragm may not work correctly on post-1961 cameras, and later MC/MD tabs may hit a screw of the front cover on earlier cameras. Four design enhancements, all forwardly inclusive and backwardly compatible, are: # SR - 1958-1966: Plain SR-bayonet featuring automatic diaphragm. Lenses are labelled ''Rokkor'' (pre-set) or '' Auto Rokkor'' (automatic diaphragm) # MC - 1966-1977: Meter coupling a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lens Mounts
A lens mount is an interface – mechanical and often also electrical – between a photographic camera body and a lens. It is a feature of camera systems where the body allows interchangeable lenses, most usually the rangefinder camera, single lens reflex type, single lens mirrorless type or any movie camera of 16 mm or higher gauge. Lens mounts are also used to connect optical components in instrumentation that may not involve a camera, such as the modular components used in optical laboratory prototyping which join via C-mount or T-mount elements. Mount types A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock (friction lock) type. Modern still camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body. Screw-threaded mounts are fragile and do not align the lens in a reliable rotational position, yet types such as the C-mount interface are still widely in use ...

Minolta XE
The Minolta XE, known as the XE-1 in Europe and the XE-7 in North America, is a manual focus, 35 mm single-lens reflex camera produced by Minolta of Japan between 1974 and 1977. It was developed in collaboration with Leica Camera and has many similarities to the Leica R3. The XE uses a Leitz-Copal electronic, vertically traveling, metal blade focal plane shutter supporting exposure times of 1/1000 of a second to four seconds, plus bulb setting. In aperture priority auto-exposure mode, the shutter speed is varied steplessly; in manual mode, the shutter speeds are selected in whole stop increments. The camera has a very short shutter lag In photography, shutter lag is the delay between triggering the shutter and when the photograph is actually recorded. This is a common problem in the photography of fast-moving objects or animals and people in motion. The term narrowly refers only ... of about 38ms, among the best for an SLR regardless of manufacturer. Image:Verschlusszeiten ...

Tele-converter
A teleconverter (sometimes called tele extender) is a secondary lens mounted between a camera and a photographic lens which enlarges the central part of an image obtained by the lens. For example, a 2× teleconverter for a 35 mm camera enlarges the central 12×18 mm part of an image to the size of 24×36 mm in the standard 35 mm film format. Teleconverters are typically made in 1.4×, 1.7×, 2× and 3× variants, with 1.4× and 2× being the most common. A 2× teleconverter doubles the apparent focal length of a given lens. Teleconverters also decrease the intensity of the light that reaches the film plane (or sensor) by the square of its magnification. A 2× teleconverter reduces the light to 1/4, doubles the focal ratio and halves the resolution of the master lens it is connected to. This, however, does not necessarily halve the resolution of the digital image. A closely related device reduces the focal length. It is generally marketed under the name sp ...

Depth Of Field
The depth of field (DOF) is the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image captured with a camera. Factors affecting depth of field For cameras that can only focus on one object distance at a time, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus. "Acceptably sharp focus" is defined using a property called the "circle of confusion". The depth of field can be determined by focal length, distance to subject, the acceptable circle of confusion size, and aperture. Limitations of depth of field can sometimes be overcome with various techniques and equipment. The approximate depth of field can be given by: : \text \approx \frac for a given circle of confusion (c), focal length (f), f-number (N), and distance to subject (u). As distance or the size of the acceptable circle of confusion increases, the depth of field increases; however, increasing the size of ...

Samsung NX-mount
The Samsung NX-mount is the lens mount used on NX series mirrorless interchangeable lens cameras by Samsung. The mount was first implemented in the Samsung NX10, and Samsung initially referred to the NX line as 'hybrid digital cameras', citing their combination of attributes of both DSLR and compact cameras. The mount is designed for APS-C image sensors, with a 1.54x crop factor. Optical image stabilization is featured on some of the lenses, indicated by an "OIS" marking. Automatic focusing on NX lenses is handled by a dedicated electric motor built into the lens. Samsung NX lenses (with some early exceptions) include i-Function (iFn), which allows control of various camera settings via a ring and button on the lens. NX5 and NX10 cameras support iFn since firmware 1.10 and 1.20 respectively, while all subsequent models support iFn natively. NX lenses Samsung NX lenses are listed in the following sortable table. ;Table Notes Samyang Optics (Bower, Rokinon, Walimex) lense ...

Canon RF Lens Mount
The Canon RF lens mount is an interchangeable-lens mount developed by Canon for its full-frame mirrorless interchangeable-lens cameras, and featured first by the EOS R, followed by the EOS RP. The RF mount was announced in September 2018. In May 2022, Canon announced APS-C EOS R cameras (the EOS R10 and EOS R7) and RF-S lenses designed for these cameras. The RF mount allows for the use of Canon EF and EF-S mount lenses using one of three Canon-made lens adapters. When an RF-S or EF-S lens is attached, however, the camera will only function as an APS-C camera, not a full-frame camera. Details Canon full-frame cameras have used the EF lens mount since 1987. In comparison with that mount, the RF mount's inner diameter is the same at 54 mm. The RF mount's flange focal distance at 20 mm is much shorter than that of the Canon EF and EF-S mounts at 44 mm. The EF-M mount has a flange focal distance of 18 mm. An EF-EOS R lens adapter enables Canon EF, EF-S, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
